The Outlook CalDav Synchronizer supports:

Auto discovery of calendars and address books

Configurable sync time range filter

Integrated groupware,
chat and project management

Nextcloud features tightly integrated chat, project management, mail, calendaring and more. Chat messages can be directly transformed into tasks, task deadlines are visible in the Calendar and files can be attached to a task from the sharing dialog.

A single platform means there is no need to juggle different accounts, keep track of where in the many cloud platforms the latest version of a document is floating around, or worry about security threats and invisible costs.

Nextcloud fluently integrates into your existing infrastructure while also providing its own. Note that Nextcloud Mail is a client for IMAP-infrastructure; Nextcloud does not include a mail server.
